Definitions
- the present invention relates to a binder, which has excellent adhesion and thermal bonding characteristics and is useful for a high-capacity electrochemical device comprising multiply stacked electrochemical cells, an electrode comprising the same binder, and an electrochemical device, preferably a lithium secondary battery, having improved overall quality by using the same electrode.
- lithium secondary batteries developed in early 1990's, have a drive voltage and an energy density higher than those of conventional batteries using aqueous electrolytes (such as Ni-MH batteries, Ni-Cd batteries and H 2 SO 4 -Pb batteries), and thus are spotlighted in the field of secondary batteries.
- aqueous electrolytes such as Ni-MH batteries, Ni-Cd batteries and H 2 SO 4 -Pb batteries
- lithium secondary batteries have a problem related to their safety, due to ignition and explosion caused by the use of an organic electrolyte.
- lithium secondary batteries have a disadvantage in that they are manufactured via a relatively complicated manufacturing process.
- a lithium ion polymer battery developed recently, can improve the aforementioned problem and disadvantage of a lithium ion battery, and thus has been regarded as one of the most potent candidates for next- generation batteries.
- a lithium ion polymer battery shows a relatively lower capacity as compared to a lithium ion battery, and has an insufficient discharge capacity, particularly at low temperature.
- the capacity of a battery is in proportion to the content of an electrode active material, it is very important to design a cell structure in such a manner that as much an electrode active material as possible can be packed in a limited space provided by a battery pack.
- 2001-0082058 and 2001-0082059 disclose an electrochemical device, which is manu- factured with ease and has an efficient space structure sufficient to maximize the amount of an electrode active material, the electrochemical device comprising multiply stacked electrochemical cells.
- the basic unit of the stacked electrochemical cells is a full cell or a bicell.
- Characteristics of a full cell or a bicell largely depend on the electrode, electrolyte and other materials used therein. Particularly, because the content of the active material introduced into an electrode is ultimately related to the maximum amount of lithium ions capable of binding, the capacity of a battery is in proportion to the content of an electrode active material. Hence, if a binder having excellent adhesion so as to reduce the amount of a binder, it is possible to provide an electrode comprising an active material in an amount increased accordingly. Therefore, there has been a need for a novel binder having excellent adhesion.
- PVDF-based polymers include PVDF homopolymer, and PVDF copolymers such as polyvinylidene fluoride- hexafluoropropylene copolymer (Korean Laid-Open Patent No. 2001-0055968) and polyvinylidene fluoride-chlorotrifluoroethylene copolymer.
- PVDF-based polymers are advantageous in that they are chemically and electrochemically stable.
- the present invention has been made in view of the above-mentioned problems.
- the inventors of the present invention have prepared binders by polymerizing copolymerizable monomers, forming a binder, with various compositional ratios.
- the inventors have found a binder composition, which uses water as a dispersion medium, and thus is environmentally-friendly, imparts sufficient adhesion between a collector and an active material even when used in a small amount to provide a battery with high-capacity, and maintains adhesion after thermal bonding to provide excellent thermal bonding characteristics between an electrode and a separator, so as to be used in a high-capacity electrochemical device comprising multiply stacked electrochemical cells.
- the present invention is based on this finding.
- the present invention is characterized by providing an environmentally-friendly binder, suitable for the production of a novel electrochemical device, which is manufactured via a simple process compared to a conventional process for manufacturing cells, and utilizes its inner space more efficiently so as to obtain high capacity.
- an environmentally-friendly binder suitable for the production of a novel electrochemical device, which is manufactured via a simple process compared to a conventional process for manufacturing cells, and utilizes its inner space more efficiently so as to obtain high capacity.

- the binder contains a maximized amount of monomer capable of controlling adhesion property while ensuring its physical stability. Hence, the binder can maintain the adhesion between an electrode and a separator continuously even during and after carrying out hot fusion. Accordingly, it is possible to improve the structural stability of an electrode and multiply stacked electrochemical cells comprising the electrode, thereby improving the lifespan characteristics of the device. At the same time, it is possible to improve the rate characteristics of a battery through the activation of electrode reactions, caused by the efficient space structure of the electrochemical device in which a plurality of unit cells are stacked so as to realize high capacity.

- the (meth)acrylic acid ester monomer is used preferably in an amount of 20-79 parts by weight per 100 parts by weight of the binder polymer according to the present invention. If the (meth)acrylic acid ester monomer is used in an amount of less than 20 parts by weight, adhesion characteristics of the binder may be degraded significantly. If the (meth)acrylic acid ester monomer is used in an amount of greater than 79 parts by weight, it may not be possible to prepare the binder itself because of low stability of the binder during the preparation thereof.
- the vinyl monomer is used preferably in an amount of 20-60 parts by weight per 100 parts by weight of the binder polymer, but is not limited thereto. If the vinyl monomer is used in an amount of less than 20 parts by weight, it may not be possible to prepare the binder itself because of low stability of the binder during the preparation thereof. If the vinyl monomer is used in an amount of greater than 60 parts by weight, the binder shows a significantly decreased adhesion value because such a large amount of vinyl monomer increases the glass transition temperature.
